I am using Champion N4G plugs, don't rate Champions never have, but I do have a pair spare. As a rule on old bikes I use new old stock plugs which have glazed ceramic tips (interesting item on Green Spark Plug website)
https://www.gsparkplug.com/shop/fouling-shortingout-problem-modern-plugs-champion-vs-ngk/I once had a 750 Ducati from the 70's that destroyed modern plugs every other time it started (often just one plug) as it wanted flooding to start. Cured by fitting ancient KLG plugs which were NOS
BUT what plugs made ages ago would the Silk like ??
I don't like the really big fat yellow spark its doing now or the fact that on switch on the ammeter goes to 6A then slowly drops to zero until I kick it. This might indicate the Boyer is switching off the coils when static as they are draining too much current.
Lucas 6V coils (17M6) - 1.5 to 2.2 Ohms between the low-tension terminals.
4 KOhms between either l-t terminal and the h-t terminal
infinte Ohms between any terminal and the case.
I will test the resistance later today but have ordered a pair of new Lucas coils anyhow. These will be Indian made Green Box Lucas (they have had a Indian owned co there for ages I think) Fitting new coils transformed a Bonny I had a few years ago
Electrics ...yuk! cannot fix them with a hammer can you??
